![]() This eliminates a large part of the loading and unloading of the components, the intermediate transportation and the quality losses due to clamping faults in the subsequent machining processes. The main advantage of the above-mentioned process integration is that the components can be finished without or at least with fewer downstream machines. In recent years, skiving has made a quantum leap in industrial manufacturing with the availability of modern control technology for spindle synchronization, tool technology for high-performance cutting and a machine structure that meets the high demands for rigidity and dynamics. While the traditional alternative processes for gear machining such as broaching, gear shaping and gear hobbing are mainly used in technology-specific special machines, gear skiving can be applied on special machines and on modern 5-axis machining centers. The smaller the axis cross angle, the closer towards the interference contour can be machined. 30 to 50 %) in comparison to the likewise flexible gear shaping and the ability to apply the gearing close to an interfering contour (workpiece shoulder). Significant for the skiving process is the short machining time (approx. The cutting speed results from the rotational speeds of tool and workpiece in relation to the axis cross angle. In this way the tooth space is “peeled out” of the workpiece in several cuts. By superimposing a feed motion, both add to the movements to the feed speed and guide the cutting edge along the workpiece axis. With the coupled rotation of workpiece and tool, a relative movement of the cutting edge in the tooth space is thus created. The skiving process is characterized by the tool and workpiece axes arranged in a certain relationship to each other – the axis cross angle. In addition to traditional gear machining processes such as hobbing, gear shaping and broaching, skiving is a continuous machining process for soft and hard machining of internal and external gears. “Power Skiving” makes a significant contribution to each of these aspects. As with all manufacturing technologies, quality, cost optimization, flexibility and productivity are the top issues. ![]() The use of planetary gears for reduction or as a differential in the drive system also increases the demand for internal gears. With e-mobility, a market is now growing which demands high precision (low running noise), high power transmission (torque and speed) from the product and equally high product flexibility in volume production. ![]() ![]() Like electric mobility, the technology of power skiving has been known for more than 100 years and, with the availability of 5-axis machining centers, has found its way into individual and series production due to its convincing process flexibility. ![]()
